JAMES T. JENKINS, OF GLEMENTS, CALIFORNIA.

WEDGE-CUTTER.

FJPECIFECATEON forming part of Letters Patent No. 318,74r7, dated May26, 1885.

Application filed December 30, 1884.

T0 aZZ whom it may concern:

Be it known that I, JAMES T. J ENKINS, of Clements, in the county of SanJoaquin and State of California, have invented a new and ImprovedlVedgeOutter, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a new and improved device forcutting wooden wedges rapidly and all of uniform shape and size.

The invention consists in the combination, with a forked block, of asliding blade connected by a connecting-rod, with an anglelever pivotedin the closed end of the block. The block is provided with screws foradjusting the gage for the piece of wood from which the wedge is to becut, and a block is held in the top of the forked block, against whichthe cutting-edge of the blade strikes.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a plan view of my improved wedge-cutter. Fig. 2 is alongitudinal sectional elevation of the same on the line 00 :20, Fig. 1.Fig. 3 is a cross-sectional view of the same on the line 1 3 Fig. 2.

A forked wooden or metal block, A, has a grooved guide, B, secured onthe upper edge of each shank O, and between the said guides a cutter orblade, D, slides on the upper edges of the shanks, the cutting-edge ofthe blade being toward the closed end of the block. The said blade isconnected by a curved connecting-rod, E, with the angle of ananglelever, F, pivoted at the end of its short arm in the closed end ofthe block, and having a handle, G, secured on its long arm. In atransverse recess in the top of the block, at the inner ends of theprongs of the fork, a block, H, is held, against which the end of thepiece for the wedge takes while being operated upon. A cross-piece, J,is secured to the bottom edges of the prongs at their inner ends, andthrough the said piece a set-screw, K, is passed. A stirrup, L, issecured on the free ends of the prongs and projects below the bottom,and in one shank of the stirrup a setscrew, M, is held, which passesthrough one (Modeh) prong of the fork. The blade D has its bottomslightly hollow -ground at the cuttingedge, and on its top it has ashort steep bevel, a, at the cutting end and a longer flat bevel, b,behind the bevel a. An ejector, composed of a spring wire, 0, connectedwith the angle of the angle-levcr F, passes through a longitudinalaperture, 1?, and projects in between the prongs G from the inner endsof the same, as shown in Fig. 2. The said wire also passes through agroove, Q, in the top of the gageblock R, placed between the prongs G,and bears against the blade D.

The operation is as follows: The gageblock R is placed between theprongs O and adjusted in the proper position for the wedges to be cut bymeans of the screws K and M. The thickness and taper desired can thuseasily be adjusted by lowering or raising either end of the gage. Thehandle G is raised, and the piece of wood from which the wedge is to becut is placed upon the gage and against the block H. The handle G isthen pressed down, whereby the cutting-edge of the blade is forced inthe direction of the arrow a into the end of the piece of wood, which isthus split by the short bevel a of the blade. The piece or block of woodis then removed, the handle G is pressed down still farther,and thesurface of the piece of wood split from the block by the short bevel ais shaved off cleanby the blade. The handle G is then raised, wherebythe blade is withdrawn and the wedge formed is thrown out at the back ofthe blade by the wire 0. Afresh wedge can then be cut. Theconnecting-rod E is curved, so as not to interfere with plac ing thepiece of wood upon the gage.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with the forked block A, of the sliding blade D, theconnecting-rod E,the angle-lever F, pivoted on the closed end of theblock A, and of the block H,held trans versely in the top of the blockA, substanstantially as herein shown and described.

2. The combination, with the forked block A, of the sliding blade D, theanglelever F, pivoted in the closed end of the block, and of theejector-wire 0, passed through the block A and connected with the leverO, substantially as herein shown and described.

3. The combination, with the forked block A,the reciprocating blade D,held to slide on said forked portion, the stirrup L, and crosspiece J,connecting the arms of the fork below the blade, the horizontal screwM, passing through one arm of the stirrup and fork, the vertical screwK,passing up through the piece J into the space within the fork, and thegage R, adapted to be held in proper position by said screws,substantially as set forth.

4:. The combination, with the forked block A, of the blade D, held toreciprocate on the arms of said fork, and having its cutting endbeveled, as shown at a b, and a gage-block, R, adjustably securedbetween the arms of the fork below the said reciprocating blade,substantially as set forth.

5. The combination, in a wedge cutter with a block, of a blade mountedthereon, a lever pivotally connected with the block and blade forreciprocating the latter, and an ejector connected to the said lever,extending therefrom to a point below the blade and adapted to eject thecut wedges, substantially as set forth. r

6. The combination, with the forked block A, of the sliding blade D,connected by a connecting-rod with a pivoted lever having a suitablehandle, a gageblock placed between the prongs of the fork, and screwsfor adjust ing the gage-block, substantially as herein shown anddescribed. v

7. The combination, with the forked block A, of the sliding bladeD,connected by a connecting-rod with a pivoted lever having a suitablehandle, the gage-block R, having a groove, Q, a spring ejector-wire, 0,connected with one end of the angle-lever and passed through the groove,and screws for adjusting the gageblock, substantially as herein shownand described.
